Patent FR-2368993-A1 (FR)
Title: Ion exchanger esp. for use as water softener - comprises rigid outer casing in which is placed pliable bag for holding the resin, allowing easy removal for regeneration of the resin
IPC: B01J47/02
Filed: 1976-10-28
Abstract: Ion exchanger particularly for use as a water softener. The apparatus comprises the conventional rigid outer casing but with the resin contained in an inner pliable and extensible bag placed within the casing. The shape of the bag adapts to fit the internal dimensions of the outer casing. The bag is made of hydrophilic material to ensure that the water passes through the resin and does not pass through any spaces between the bag and the outer case. The outer case is closed by a lid which is easily removed for the withdrawal of the bag. When the resin needs to be regenerated, it is only necessary to send the resin within its bag. This avoids high transport costs and the danger of breakage which occur if the whole appts. has to be transported.

Patent FR-2368251-A1 (FR)
IPC: A47J31/56
Filed: 1977-10-13
Abstract: This coffee-making machine has a metering vessel (G) for receiving hot water, a brewing funnel (B) for receiving ground coffee, and a control device (N). In the metering vessel (G) there are two level electrodes (ET, EK) for metering the hot water for a cup or a pot of coffee, and a minimum electrode (Emin). Arranged between the metering vessel (G) and the brewing funnel (B) is a pressure-dependent separating device in the form of a rising pipe (S). By this means, the metering vessel (G) is separated from the brewing funnel (B) during the metering of the hot water. The supply of hot water to the metering vessel (G) can be switched on by means of a switch (T, K) and is switched off when one of the level electrodes (ET, EK) has been reached. The relevant level electrode (ET, EK) is connected to a device (R2) for automatically switching on the supply of steam on completion of the metering of hot water. Owing to the pressure of the steam entering the metering vessel (G), the hot water is pushed via the rising pipe into the brewing funnel (B).

Title: Drilling tool for increasing dia. of petroleum wells - incorporates cutting arms closed for entry, opened for working by pistons under pressure of lubricating sludge
IPC: E21B10/32
Filed: 1977-11-08
Abstract: The tool comprises a long hollow cylindrical body having a connecting part, a first piston, a second piston, cutting arms and a guiding head. The connecting part allows the tool to be joined to a train or rods. The first piston can be displaced under the action of the lubricating sludge and is provided at its lower part with a pin-valve which can be moved against the action of a spring. The second piston can be displaced against the action of a second spring to open the cutting arms, which are mounted on axes intergal with the main body. The arms pivot about the axes to a position in which each is locked by a shoulder on the shank of the second piston. The lower outer part of each arm is triangular in shape, giving large surfaces which are covered with projecting stones, e.g. industrial diamonds, capable of cutting the ground. The lower inner part of each arm is hollowed and provided with projecting stones, but allows the expulsion of debris towards the surface. The guiding head can also carry projecting stones on the its outer worker surface. The invention makes good the deficiencies of existing tools, e.g. high cost, slowness of operation, abnormal wear and breakages etc.

Title: Crop dryer which uses warm air recycled via heat pump - and evaporator which condenses out moisture and condenser which raises air temp.
IPC: A23N12/08
Filed: 1977-11-10
Abstract: The installation now comprises a vertical silo contg. the crop to be dried. Hot air is blown upwards through the contents of the silo and recycled via a vapour compression refrigeration plant employed as a heat pump. Air from the silo is passed first through the evaporator, to be cooled and lose moisture by condensation. The dried air is then directed through the condenser to raise the temp. of the air prior to recycling through the silo. The installation pref. comprises an elevator which periodically lifts prod. from the base of the silo and returns it to the top. The complete installation is pref. enclosed in a thermally insulated casing. Several silos are pref. arranged around a central elevator which recycles the contents of each silo in turn. Crop dryer is partic. for cereals such as wheat, maize etc., vegetables such as peas and beans, fruits such as plums and nuts such as almonds. High thermal efficiency is achieved by insulating the complete installation and using both the evaporator and condenser units of the refrigeration plant. Pre-filtered air is continually recycled so that there is no danger of contaminating the crop with external smells and flavours.
